Concrete Repairs & Leveling

This request is for concrete repairs and leveling needed per OSHA 1910D and ADA requirements. Please review the specification document to view necessary details and images related to the scope of work.The bidding specifications are as follows:  Spalling and deterioration of concrete in eight (8) areas as noted below to be repaired.  Some areas will require removal and replacement, while others may allow for patching. The approximate square footage is approximately 3,520 sq.ft. where repairs need to be made. One (1) of the eight (8) concrete sections is a lamp post base that has previously been repaired that needs to be re-repaired or demolished and replaced.
Seven (7) concrete sections located in the front entrance of 4200 Surface Road facility in solid red outline must be leveled to meet OSHA 1910D and ADA requirements of ¼” maximum height change (vertical) and gap (horizontal) on walking surfaces. One (1) concrete section outlined in blue may be ground or leveled.
 
Clean out and seal all construction, expansion, and isolation joints.
 
Access to the main entrance of the facility must be maintained from 6am – 6pm Monday through Friday. If access to the facility can be maintained, the work can be completed in segments; however, if facility access cannot be maintained, work will need to take place after hours.
 
Windows must be protected from damage. All debris must be cleaned up. If ground, a sealer needs to be applied.
 
To fill gaps larger than ¼” between concrete slabs, use a flexible, non-sagging caulk designed specifically for expansion joints, which allows the concrete to move while preventing water and weeds from entering the gap; for larger cracks or voids,  a concrete patching compound or a sand-cement slurry to fill the space depending on the size and location of the gap.
